I can't wait to make this!
I was just wondering... if I opt to use some 575L roast barley, should I still use the same proportions? In my BS recipe I have 1lb for a 5.5gal batch (65% efficiency... no grain mill!) and the recipe comes out to 4.2% ABV, 32.7SRM, and 30.5 IBU's.
I think it'll be fine, but a little support would make me feel better

haha
